Long time ago i bought the "Delphi 4 Developers Guide". There was an example how to show a video in this example it was in .avi format) it eas shown on a Panel. Not on a Memo.
But for your plan, maybe it is better to use a TBrowser component. Such component should have suitable functionality for including your frame code.
yes iam planing to use embedded WB but i dont know what to use to convert an actual video
url to embbedded code
